Skin effect in audio cables is the tendency for excessive frequency indicators to journey greater at the surface than in the center of the conductor, as though the conductor have been a hollow steel pipe.[3] this tendency, resulting from self-inductance, makes the cable more resistant at higher frequencies, diminishing its ability to transmit high frequencies with as a whole lot power as low frequencies. As cable conductors growth in diameter they've much less general resistance however elevated skin effect. The selection of metals within the conductor makes a difference, too: silver has a more skin effect than copper; aluminum has less impact. Skin impact is a widespread problem at radio frequencies or over lengthy distances inclusive of miles and kilometers worth of high-tension electric transmission traces, but not at audio frequencies carried over brief distances measured in feet and meters. Speaker cables are normally made with stranded conductors however naked metallic strands in touch with every different do no longer mitigate pores and skin effect; the package of strands acts as one conductor at audio frequencies.[7] litz wire – individually insulated strands held in a selected sample – is a form of high-cease speaker wire intended to reduce pores and skin effect. Any other answer that has been attempted is to plate the copper strands with silver which has much less resistance.[8].

Resistance is by using far the most important specification of speaker wire.[4] low-resistance speaker cord allows more of the amplifier's energy to energise the loudspeaker's voice coil. The overall performance of a conductor which includes speaker twine is therefore optimised by means of limiting its duration and maximising its pass-sectional place. Relying at the listening to capability of the listener, this resistance starts offevolved to have an audible effect when the resistance exceeds 5 percentage of the speaker's impedance.[4].
